从ElementUI的官网新建了VUE组件，使用这段代码

<template>
  <el-table
    :data="tableData"
    style="width: 100%">
    <el-table-column
      prop="date"
      label="日期"
      width="150">
    </el-table-column>
    <el-table-column label="配送信息">
      <el-table-column
        prop="name"
        label="姓名"
        width="120">
      </el-table-column>
      <el-table-column label="地址">
        <el-table-column
          prop="province"
          label="省份"
          width="120">
        </el-table-column>
        <el-table-column
          prop="city"
          label="市区"
          width="120">
        </el-table-column>
        <el-table-column
          prop="address"
          label="地址"
          width="300">
        </el-table-column>
        <el-table-column
          prop="zip"
          label="邮编"
          width="120">
        </el-table-column>
      </el-table-column>
    </el-table-column>
  </el-table>
</template>

<script>
  export default {
    data() {
      return {
        tableData: [{
          date: '2016-05-03',
          name: '王小虎',
          province: '上海',
          city: '普陀区',
          address: '上海市普陀区金沙江路 1518 弄',
          zip: 200333
        }]
      }
    }
  }
</script>

router里的index文件

import Vue from 'vue'
import Router from 'vue-router'
import NewFile from '@/components/NewFile'

Vue.use(Router)

export default new Router({
  routes: [
    {
      path: '/NewFile',
      components: {
        newfile: NewFile,
      }
    }
  ]
})

src下的App.vue和Main.js文件

<template>
  <div class="container" id="vueApp">
    <router-view name="newfile"></router-view>
  </div>
</template>

<script>
export default {

}
</script>

<style>
</style>

import Vue from 'vue'
import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';
import Table from 'element-ui';
import App from './App'
import router from './router'
import store from './store'
import 'babel-polyfill'

Vue.config.productionTip = false
Vue.use(ElementUI);
Vue.use(Table);

/* eslint-disable no-new */
new Vue({
  el: '#app',
  render: h => h(App),
  router,
  store,
  components: { App },
  template: '<App/>'
})

package.json里的依赖：

"dependencies": {
    "axios": "^0.19.0",
    "babel-polyfill": "^6.26.0",
    "element-ui": "^2.13.0",
    "express": "^4.17.1",
    "mysql": "^2.17.1",
    "vue": "^2.5.2",
    "vue-axios": "^2.1.5",
    "vue-router": "^3.0.1",
    "vuex": "^3.1.2"
  }

单独新建一个VUE项目可以运行，但是在原有这个项目运行无法渲染页面，并弹出以下问题，不知道有无相关

另外elementUI的其他组件，比如el-form和el-dialog，做登录页时也是单独项目可渲染，但是在这个项目里无法渲染，但是也没有相关报错，求大佬指教
